To all whom it may concern:

Be it known that I, EMIL H. lV. ULLRICH, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of illinois,have invented certain new and useful Improvements in Receptacles, ofwhich the following is a specification.

My invention relates to receptacles and involves improved application ofcovers thereto.

The invention concerns particularly sheet metal receptacles having sheetmetal slip covers, that is, covers which merely slip over the receptaclemouth as distinguished from such covers as, for example, are screwthreaded to the receptacle. It is very desirable in receptaclescontaining certain classes of goods that the covers engage accuratelyand with sealing fit to prevent spoiling or deterioration of thecontents, and that the covers are locked` against displacement orremoval in order that the receptacles may be handled and shipped withoutdanger of the covers coming olf. It is also desirable, particularlywhere the goods in a receptacle are to be gradually drawn upon and used,that the cover may be applied in such manner as to seal the receptacleto prevent leakage of the contents, while at the same time to be readilyremovable and readily accurately replaced. For example, wherereceptacles contain coffee, tea, spices, and allied goods, it isdesirable that the covers be adapted for sealing and interlockingengagement with the receptacles so that they can be stored as stock andreadily shipped without danger of spoiling or leakage of the contentsand without danger of the covers accidentally coming oil". It is alsodesirable with this class of goods that the housewife, for example, mayreadily unlock and remove the cover and then be able to apply the coverso that while it will still seal the receptacle it can be more readilyremoved at any time that it is desired to draw on the contents. Asanother example, shoe-blacking receptacles may be cited. lVith thisarticle it is very desirable that the receptacles be absolutely sealed.to protect the contents and that 'the cover be locked againstdisplacement when the receptacles are in stock or handled and shipped.On the other hand, it is very desirable, after the first unlocking andopening of the cover, that the cover can be applied and removed morereadily while at the same time it will fully seal.

The above features are also desirable in receptacles for containingpaints, varnishcs, ink, soap, and in fact any material which should besealed to be preserved and whose use from time to time necessitatesrepeated opening and closure of the containing receptacle.

The object of my invention is therefore More in detail, the inventioninvolves the provision of beading or grooving on one part withcorresponding grooving and beading on the other, the disposition beingsuch that the grooving and heading will engage and interlock only afterconsiderable force has been applied to the cover, while if only aslighter force is applied to the cover it will have a slip and sealingfit without interlocking and to be readily removed or applied.

The construction and arrangement, togethcr with its useful results willbe clear 'from the following specification together with theaccompanying sheet of drawings in Which- Figure l is an elevational viewof a receptacle with part broken away to more clearly show theconstruction and arrangement, the cover being shown fully applied andlocked. Fig. 2 is asimilar view ot' the upper part of the receptacleshowing the cover unlocked but still scaling the receptacle, Fig. 3 is asectional view of `the corner of a receptacle showing a modifiedarrangement, the cover being fully closed and locked, lrig. 4 is asimilar view showing the cover partly unlocked, Fig. 5 is a sectionalView of the corner of a receptacle showing the cover licked, Fig. 6 is asimilar view showing the cover applied but unlocked, Fig. 7 is a similarview showing the cover inverted and sealing the receptacle, Fig. 8 is aperspective view of one half of the y upper partof a receptacle showingthe invention applied to a polygonal receptacle, and Figs. 9 and 10 aresectional views of the upper corner of'a receptacle showing othermodified arrangements.

In Fig. 1 I have shown a receptacle comprising a cylindrical body l0,the base 11 and the cover 12. As shown, the body near its upper edge hasthe exterior vannular groove 13 and thecover has in its flange 12 theinternal annularwidge or bead 14 for engaging in the groove 13 when the`cover' is fully applied, the cover'being then locked in place. areceptacle is filled in order that its contents will be protected whenthe receptacle is put in stock or shipped. lot only do -the bead andgroove. interlock to hold the cover in place but a more effectivebarrier or seal is provided against leakage or against entrance of air.As special force is necessary to apply the cover in locking position itwill also require extra force to unlock the cover. As shown7 the usualexternal ridge or bead 15 is provided on the receptacle below the coverflange, in order that a suitable implement can be applied between thisbead and the cover flange to pry the cover upwardly to effectdisengagement of the locking bead `and groove. To give better pryingsurface to the cover the flange end may be curled over as indicated at16, such curling also greatly strengthening the cover. Vith thisarrangement the cover can readily be unlocked by applying a screw driveror knife, or any other suitable implement or object between the bead l5and the cover end 16, and after disengagement of the locking grooveandbead the cover can be readily entirely withdrawn to open thereceptacle. After the receptacle is thus opened and the intention'is todraw on the contents from time to time, the cover need not be fully apiThe' cover is thus applied after.

the base of the flange 10,. If 'greater security of the cover is desireda little greater l force may be applied and the cover pushed downfurther until its bead interlocks with the groovel, It will be readily`understood that thebeadi'ng'- 14 may be `continuous or sectional, thatis, the bead may yextend entirely around the cover or shorter beadsmaybe provided at intervals for engaging with the continuous groove 13. l

In Figs. 3 and 4 a modified arrangement is shown, the body 10 beingprovided with an A additional groove 13 below the groove'13 and thecover being provided with additiohal beading 14" below the beading 14,the,

beading 14 and 14 interlocking with the fgrooving 13 and l-3respectively when the readily removed by hand from the positionv shownin Fig. 4. Instead of applying the cover up to the top heading it couldof course be applied only until the lower beading 14 reaches the flange10 in which position the end of the cover flange below the heading 14would have a slip and sealing fit plied to interlocking position withthe re.-v

ceptacle but need be slipped on to thereuceptacle only until the bead 14reaches the i upper edge of the body, the slip engagement of the sectionc of the flange with the sides of the body being thenisufficient toeffect sealing and to hold thacover in place under all ordinaryconditions. "The bead 14 forms an abutment for determining lthe distanceof application of the cover, and engagement of the bea'd with the edgeof the b'ody\"10 will also va'ssistvin sealing the receptacle."\ orderthat the covery may be more readily "1;

applied the upper section 10 or the body 10 is deflectedinwardly-'slightly as shown in Fig. 2. to form an inclined` annularguide \flange for the lower edge 16 of the cover..

Then the covcrfisthen applied this edge 16 will be guided by the flange10 into and centered with reference to the receptacleg' whereupon aslightpressure will carry the `cover down until the bead 14 abutsagainst with the receptacle body and the cover couldvery readily beremoved when desired Without the aid of any implement." l

In Figs. 5, 6 and 7 another modified arrangement is shown, theconstruction of thev body being the same as in.Figs. 1 and v2 exceptthat the upper part e thereof is' curled inwardly to give the so-calledfalse wire? effect and to-provide the cylindrical seat 17. The flange ofthe cover is the same as in Figs. 1 'and 2 but the top of the cover iscentrally deflected upwardly to form the dome'18, the cylindricalsection 18 at the baseI of the dome being of external diameter toVSnugly"fit the seat 17 when the cover is applied after invertionthereof, the flat peripheral section 19 of the cover surrounding thedome then engaging with the top of. the body 10 as indicated i-n Fig. 7.lVith this a rangement when the cover is applied in the ordinary mannerits flange 12 will slip fit the bodyflO and when the beading 14 engagesand interlockswith the groove 13 the hover will befsecurely locked tothe receptacle with sealing fit asindicated in Fig. After the cover hasbeen forced open it may thereafter bevapplied only part way until rthe'-bead 14 abuts against the end of the body as shown in Fig. 6, or it maybe in verted and applied with its dome inserted into the receptacleoutlet and seating against the seat 17 as shown in Fig. 'l'.I When thecoier is applied as shown either in Fig. 6 or Fig. 7, the receptacle issealed but the cover can readily be withdrawn by hand and can readily beapplied as the contents olE the receptacle are drawn upon. When thecover is inverted it forms a receptacle which can be used for measuringor other purposes. For example it could be used as a mixing receptacleby painters.

In Fig. P an arrangement is shown involving the features of my inventionand which is particularly adaptable to receptacles of polygonal shape.Insuch receptacles, particularly where the sides are of considerablelength, the edges f thc sides might buckle or bow when the cover isapplied and the receptacle would not be sealed. To prevent this lpreferably deflect the innersection 20 ot' the cover top downwardly toproduce the peripheral channels Q1 as indicated in Fig. 8. whichchannels will intimately receiwe the upper ends of the sides oi' thebody l0 when the cover is ap- .plied and will prevent buckling or bowingof these' ends. Fig. 8 clearly shows how the curled over or false wireends e are intimately held in the channels. The channels 'could have thesaine curvature as the ends e to snugly fit throughout when the cover isapplied to thus give a very effective seal. lVhen the cover is Jullyapplied the bead 14 thereon will interlock with the groove 13 on thereceptacle body and will securelyhold the cover in place. When thecfiver 1s unlocked and removed it can then be replaced only sufficientlyto bring the beads 14 against the ends e and the slip fit of the coverflange below the beads will then cflect sufficient sealing 'for ordinarypurposes.

Fig. 9 shows the downwardly deflected type of cover applied to a bodyhaving its upper edge deflected to form the flange l0 as in Figs. l andQ. "he channel sections 2l of the cover intimately receive the flangesections 10 when the cover is Yfully applied and will prevent bucklingor bowing in order to maintain a sealing fit between the cover flangesections and the side sections oli the body 10.

Instead of having an external groove provided on the receptacle body andan internal bead on the cover flange. the body could have an externalbead E22 and the cover an internal groove Q3 as illustrated in lt).lVhen the cover is fully applied its groove would'interlock with thebody bead. and when the cover is partly applied the body bead would actas an abutment for the lower edge of the cover flange. lit is alsounneces sarv to curl up or bead the lower edge ot the cover flange, butthis is desirable particularly in larger receptacles to stillen andstrengthen the cover flange and also to provide an abutmentft'or anunloclfif.lr ir'frple'- ment. i

do not of course desire to be limited to the exact forms andarrangements which I have shown and referredv to as others might bepossible which would still come within the scope of the invention., themain object of which is to provide for a -ocked or permanent position ofthe cover and a freer temporary position of the cover but with sealingengagement with either position.
